The 1 - D climate model uses physically based equations to
determine changes in the climate system as a result of changes in solar intensity, ice reflectance and greenhouse gas changes.

The researchers examined various reconstructions of past temperatures and CO2 levels to
determine how the
climate system has responded to previous
changes in its energy balance.
An overall objective, aside from the desire to assess alternative means to combine human social
system models with
climate models, is to provide a rational basis to
determine whether human risk perception and associated
changes in behaviors can significantly affect
climate projections.
-- 7) Forest models for Montana that account for
changes in both
climate and resulting vegetation distribution and patterns; 8) Models that account for interactions and feedbacks
in climate - related impacts to forests (e.g.,
changes in mortality from both direct increases
in warming and increased fire risk as a result of warming); 9)
Systems thinking and modeling regarding climate effects on understory vegetation and interactions with forest trees; 10) Discussion of climate effects on urban forests and impacts to cityscapes and livability; 11) Monitoring and time - series data to inform adaptive management efforts (i.e., to determine outcome of a management action and, based on that outcome, chart future course of action); 12) Detailed decision support systems to provide guidance for managing for adap

They created a model to
determine how temperatures of ocean waters could
change shallow reef
systems when sea levels rise and
climate warms
in the future.
These factors driving the present
changes of the NHSM
system are instrumental for understanding and predicting future decadal
changes and
determining the proportions of
climate change that are attributable to anthropogenic effects and long - term internal variability
in the complex
climate system.
It's the long - term range (30 - plus year cycles) that scientists look at to
determine real
changes in the
climate system, and the
changes scientists see are unmistakable.
Determining which types of prevention to invest
in (such as monitoring, early warning
systems, and land - use
changes that reduce the impact of heat and floods) depends on several factors, including health problems common to that particular area, vulnerable populations, the preventive health
systems already
in place, and the expected impacts of
climate change.275 Local capacity to adapt is very important; unfortunately the most vulnerable populations also frequently have limited resources for managing
climate - health risks.
On the question of hurricanes, the theoretical arguments that more energy and water vapor
in the atmosphere should lead to stronger storms are really sound (after all, storm intensity increases going from pole toward equator), but
determining precisely how human influences (so including GHGs [greenhouse gases] and aerosols, and land cover
change) should be
changing hurricanes
in a
system where there are natural external (solar and volcanoes) and internal (e.g., ENSO, NAO [El Nino - Southern Oscillation, North Atlantic Oscillation]-RRB- influences is quite problematic — our
climate models are just not good enough yet to carry out the types of sensitivity tests that have been done using limited area hurricane models run for relatively short times.
The comparison of human and machine capability is appropriate because of the difficulties involved
in trying to understand something like the climatic
system and
determine the effects that anthropogenic
climate change will have upon it.
the unequivocal attribution of
climate change to anthropogenic causes (i.e., the isolation of cause and effect) would require controlled experimentation with the
climate system in which the hypothesised agents of
change are systematically varied
in order to
determine the
climate's sensitivity to these agents.
The planet moves past thresholds and the
climate response is internally generated — with
changes in cloud, ice, dust and biology — and proceeds at a pace
determined by the
system itself.
Abrupt
climate change happens when the
system is pushed past a threshold and transitions to a new state that is
determined by shifts
in cloud, wind, ice, currents and biology.
«Reducing the wide range of uncertainty inherent
in current model predictions of global
climate change will require major advances
in understanding and modeling of both (1) the factors that
determine atmospheric concentrations of greenhouse gases and aerosols, and (2) the so - called «feedbacks» that
determine the sensitivity of the
climate system to a prescribed increase
in greenhouse gases.»
«TCR was originally defined as the warming at the time of CO2 doubling (i.e., after 70 years)
in a 1 % yr — 1 increasing CO2 experiment (see Hegerl et al., 2007b), but like ECS, it can also be thought of as a generic property of the
climate system that
determines the global temperature response ΔT to any gradual increase
in RF, ΔF, taking place over an approximately 70 - year time scale, normalized by the ratio of the forcing
change to the forcing due to doubling CO2, F2 × CO2: TCR = F2 × CO2 ΔT / ΔF»
